Use `<tc:stars/>` to create a five star rating.

Values can be by clicking on the stars component and slide to the desired value. To delete a value, just move the cursor to the left.

The maximum value is by default '5'. To enable half stars set `max` to '10' or '20' for quarter stars.

If no value is set, a placeholder value is displayed. The `placeholder` attribute must contain a number between '0' and '5'. Floating point numbers are allowed even if the user can only set full stars.

The placeholder value is set to '4.7' in following example.

A star component can be marked as required. If you click the submit button without setting a value, the submit fails. Once a value has been set, it cannot be deleted for required star components.

The star component can also be used with `BoundedRangeModel`. The model contains the values for the `value` and the `max` attribute.
